MACHINE FOR FOLDING AND STITCHING PAPER.

Speeilication forming part of Letters Patent No. 36.425,-dated September 9,1862.

T0 all whom t 'may concern.-

Be it known that l, J oHANN HEiuRIoH TAN- NER, of Frauenfeld, in the canton of Thurgau and Republic of Switzerland, have invented a new and Improved Machine for Folding and ,part of this specification, in which-- Figure l represents a front elevation of my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a plan or top view of the same, the top or folding table having been removed to expose the working parts of the machine. Fig. 4 is a detached elevation of the mechanism for drawing in and cutting the thread.

Similar letters of reference in the several figures denote corresponding parts.

This invention consists in the arrangement of a stitching device and pressing or smoothing rollers and of a series of folding-blades in such a manner that a piece of thread is drawn through each sheet of paper before the last fold is completed, and that when completely folded each sheet is passed by the action of a pair of take-oft' rollers through the smoothing or pressing rollers7 from which it is discharged ready for the binder.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation with reference to the drawings.

The sheets of paper to be folded are placed on a table that is to be supported by the bracket a, (see Figs. 2 and 3,) and from this table one sheet after the other is fed on the folding-table A, which forms the top of my machine. This table is supported by the standards B, which rise from the horizontal supporting-plate B and form a portion of the frame C, to which the several parts of my machine are attached.

Two several devices are applied for the purpose of holding the sheet of paper in the proper position-fthe pointed dogs Z above and the vibrating needles c below the table A. The dogs b are guided by sleeves b', which are secured by means' of setscrews b2 to a lever, b3, which receives a rising and falling vibrating motion by means of an arm, b4, cam b, connection rod be, and bellcrank lever bq,

tirst foldingblade, D, begins to act upon it.

The vibrating needles c are attached to arms o', which extend from the rock-shaft c?, to which an oscillating motion is imparted through the action of the cam d on the double-armed lever cii d, the arm c3 of which connects by a` rod, c, with a lever, c5, that is firmly attached to the rock-shaft c2. By this arrangement the' needles c are caused to penetrate the sheet of paper that may be placed on it at proper intervals, and retain sa-id sheet until the rst folding-blade, D, begins to act.

The folding-blade D is secured to a carriage, D', to which a reciprocating vertical motion on the slide D2 is imparted by the action of the cam d on the double-armed levere3 d3. This lever is fulcrated on a pivot, d', inserted into a standard, di, that is firmly secured to the frame G, and its long arm di forms a toothed segment, which gears into a pinion, d, which is secured to the outer end of a rock-shaft, d5, and which connects, by means of a lever, d, and rod dwith the carriage D'. An oscillating balance-weight, d8,which is secured to the inner end of the rock-shaft d5, facilitates the e upward motion of the carriage D and foldingblade D. Said foldingblade passes down through'a gap, a', in the table A, where the sheet of paper receives its rst fold, and it leaves the sheet thus folded between the elastic bands a2, the lower ends of which are compressed by suitable clasps, so that they retain the folded sheet while the blade D ascends. i

Before the first folding-blade,D,has entirely completed its upward motion the second folding-blade, E, commences to act on the sheet By the action of this blade the sheet of paper is carried through between two standards, et, where the same receives its second fold, and it is forced in between vthe horizontal bars ft and the elastic bands e5, the extreme :ends of which are compressed by clasps e, (see Fig. 3,) so that they retain the sheet while the folding-blade recedes. The third and last fold is imparted to the sheet of paper by the foldingblade F, to which a reciprocating motion in a horizontal plane isimparted by the action of the camfon the vibrating leverf, the upper end of which is provided with a toothed segment, that gears into a pinion, f2 on the lower end of a vertical arbor, f3, the upper end of which bears a crank, ft, that connects by a link, f5, with a pivot,f?, at the eX- treme end of the slidefl, to which thefoldingblade F is rigidly attached. The arbor f Ia has its bearing in a vertical standard, f8,w hich supports the dovetailed waysf", that form the guide for the slide f 7, and as said arbor receives an oscillating motion through the action of the lever f on the pinion f2 a reciprocating 'motion is imparted to the folding-blade F.-

Before this blade acts on the paper, however, the stitching is effected by means of two hooked needles, g, which are secured to the ends of a forked arm, g', to which a vibrating motion is imparted by means of an oscillating lever, g3, that receives its motion from a cam, g5, through the action of a lever, g, and link gl. By these means the needles receive an oscillating motion in vertical planes, and on being driven through the doubly-folded sheet of paper they receive a piece of thread and carry the ends of the same back through the paper before the folding-blade F commences to act.

The thread is taken from a spool that is placed on the hooked pin h underneath the table A,- and it is carried in through the eye i, that is inserted into aplate, j, to which the shears k are secured. In passing through the eye the end of the thread is caught between the nippers Z, which draw in a piece of the desired length,when the threadis cut anddropped on the needles g, which at this moment stand ready to receive it. A certain tension is exerted on the thread by a spring, Z', the loose end of which passes through a slot in the top of the eye and presses upon the thread, and the shears k, as well as the nippers Z, are op= erated by a slide, m, which moves in V-shaped ways m', that are firmly screwed in a vertical direction to the inner ends of the dovetailed ways j, forming the guides of the foldingblade F. Motion is imparted to the slide m by a crank, mii, which is rmly attached to the upper end of the Vertical arbor m2, which also carries the cam g5, and which connects by means of a link, m3, with a wrist-pin, m4, on the end of the slide m. From the slide m a bracket, Z', extends, to which the nippers Zare secured, and the two jaws of said nippers are so arranged that they open spontaneously. Their points are tapering and provided with a recess that forms the guide for a sliding clasp, Zz. When this clasp is moved toward the point of the nippers, the jaws-are open,

.and if the nippcrs are now moved toward the eye i the ends of the thread pass between the jaws, and now the `clasp Z2, by striking the cross-bar Z, is pushed back, causing the nippers to close and to catch hold of the thread. As the nippers recede, and ifasuficient length of thread has been drawn in, the clasp Z2, by coming in contact with the cross-bar Z, is thrown forward, the nippers open, and the thread is released; but just previous to being released the shears cnt the thread, so that as soon as the nippers open a piece of thread of the desired length drops down upon the hooked needles, which draw the same back through the paper, as previously described.

The shears lo are operated by notched lever which a vibratingmotion is imparted by theaction of a curved slotted plate, las, that is'iirmly attached to and moves with the slide m. Two notches in the lever 7c catch over the shanks or handles of the shears in such a manner that by depressing the notched end of the said 1ever the shears are opened, and by raising said in the slot la* in the curved plate k3, so that by the action of said plate as it moves backward and forward with the slide m the lever 7c is alternately raised and depressed and the shears are opened and closed. After the needles the folding-blade F produces the last' fold by. carrying `the sheet through between the barsf* and delivering to the take-oft' rollers G, to which the folded sheet is conducted over the stationary segmental guides H. The surface of the take-off rollers is fluted or made rough, so that the same readily carry in the paper and deliver it to the smoothing-rollers I. The take-oft rollers act on the sheet'of paper simply by their own gravity, whereas the smoothing-rollers are forced together by setscrews O. By the action of the last pair of rollers I the folded sheet is rendered smooth and the folds are completed, so that the sheets on being discharged from the machine are ready for being bound without requiring any further labor.

zontal shaft, p, to whichv motion is imparted throughl the gear-,Wheels q r s from the driving-shaft J. A bevel-wheel on the shaft p, by gearing into a similar bevel-wheel, t', transmits the motion to the vertical arbor m2, and a bevel-gear, u u', and cog-wheels ce transmits the motion `from the driving-shaft J tothe take off rollers G and smoothing rollers I. By this arrangement asimple and compact machine is produced, and the quantity of sheets that can be folded by the same depends entirely upon .the dexterity of the person 'feed ing the paper to the machine.
